The BSR is an OEM designed retrofit circuit breaker for both the BRUSH Switchgear VSI range of Oil Circuit Breakers and the VMV vacuum Circuit Breaker, to IEC 62271-100.
BRUSH Switchgear is proud of its heritage in the VSI, VTD & VMV range of switchgear, which continue to work at the highest standards today. Technological advances have allowed us to improve further and offer our customers a circuit breaker that boasts the magnetic actuator.
The BSR circuit breaker, offers a new lease of life for existing switchgear, with this effective retrofit solution. Employing magnetic actuator technology with vacuum interrupters, the BSR is designed for 10,000 operations and a life expectancy of 30 years. It is designed for retrofitting into existing switchboards without the need for panel modification.
|BSR Retrofit datasheet|
- Superior, proven technology with minimal maintenance
